Summary
Red Hat Security Advisory: kernel security update

Notes

Topic
Updated Itanium kernel packages that fix a number of security issues are now available.
Details
The Linux kernel handles the basic functions of the operating system. This kernel updates several important drivers and fixes a number of bugs including potential security vulnerabilities. Paul Starzetz discovered flaws in the Linux kernel when handling file offset pointers. These consist of invalid conversions of 64 to 32-bit file offset pointers and possible race conditions. A local unprivileged user could make use of these flaws to access large portions of kernel memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0415 to this issue. A flaw was discovered in an error path supporting the clone() system call that allowed local users to cause a denial of service (memory leak) by passing invalid arguments to clone() running in an infinite loop of a user's program (CAN-2004-0427). Enhancements were committed to the 2.6 kernel by Al Viro which enabled the Sparse source code checking tool to check for a certain class of kernel bugs. A subset of these fixes also applies to various drivers in the 2.4 kernel. Although the majority of these resides in drivers unsupported in Red Hat Enterprise Linux 3, the flaws could lead to privilege escalation or access to kernel memory (CAN-2004-0495). During an audit of the Linux kernel, SUSE discovered a flaw that allowed a user to make unauthorized changes to the group ID of files in certain circumstances. In the 2.4 kernel, as shipped with Red Hat Enterprise Linux, the only way this could happen is through the kernel NFS server. A user on a system that mounted a remote file system from a vulnerable machine may be able to make unauthorized changes to the group ID of exported files (CAN-2004-0497). A bug in the e1000 network driver has been addressed. This bug could be used by local users to leak small amounts of kernel memory (CAN-2004-0535). Inappropriate permissions on /proc/scsi/qla2300/HbaApiNode (CAN-2004-0587). The following drivers have also been updated: fusion to 2.05.16 ips to 7.00.15 cciss to 2.4.52 e1000 to v. 5.2.52-k1 e100 to v. 2.3.43-k1 All users are advised to upgrade to these errata packages, which contain backported security patches that correct these issues.
